Novel elevator car vibration reducing device

Abstract

The invention relates to the technical field of elevator vibration reducing devices, in particular to a novel elevator car vibration reducing device. The novel elevator car vibration reducing device comprises an upper connecting plate, a lower connecting plate and a rubber body arranged between the upper connecting plate and the lower connecting plate, wherein the upper connecting plate and the lower connecting plate are arranged in an up-and-down symmetric mode and are both rectangular, and thus the contact area between the vibration reducing device and the bottom and the bottom frame of an elevator car is enlarged; due to the fact that two holes are formed in the rubber body, large compression deformation can be generated, and good damping and vibration reducing performance is achieved; lastly, bolts are mounted in upper through holes and lower through holes in the two ends of the upper connecting plate and the two ends of the lower connecting plate, and thus the vibration reducing device is tightly and firmly connected with the bottom and the bottom frame of the elevator car. The vibration reducing device is capable of performing the dual functions of elevator overload protection weighing and elevator car vibration reducing, has good performance parameters and is high in stability.

Description

technical field [0001] The invention relates to the technical field of elevator damping devices, in particular to a novel elevator car damping device. Background technique [0002] In the vertical elevator, a vibration damping pad is installed at the connection position between the bottom of the car and the bottom frame of the car, so as to play the dual functions of elevator overload protection weighing and car vibration reduction during elevator operation. According to different rated loads of the elevator, install 4-10 damping pads on the bottom frame of the car to evenly support the car. The compression displacement of the damping pads directly reflects the load of the car. When the load reaches the rated value, then The height of the vibration damping pad will be reduced to a certain value, so that the touch sensor at the bottom of the car will contact and issue an overload alarm. . When the elevator is running, the vibration damping pad can also keep the car running ...

AI Technical Summary

Problems solved by technology

At present, elevator car shock pads generally rely on foreign imports, and domestic independent research and development and production levels are still at a relatively low level. The performance parameters and stability of elevator car shock pads cannot meet the actual application requirements.
